Description Curtis Seizert 2016-11-11 04:18:46 UTC

Application: plasmashell (5.8.3)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

Whenever I switch the source of one monitor (dual head configuration), plasma crashes when I switch back.  This pushes all windows to the monitor not switched and erases the desktop of the monitor that was switched.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
